Hello Sayan,

According to the previous year data, we assume that for 300 marks you will get rank around 6000 in NCHMCT JEE exam.

Now, To get into IHM Kolkata-

Based on NCHMCT JEE 2021 cutoff,

General category - 2306 ( Last Rank in Round 3)

SC category - 11349 (Last Rank in Round 3)

ST category - 12240 ( Last Rank in Round 3)

EWS - 6647 (Last Rank in Round 3).

So, If you have any reservation category (SC or ST) , then there will be a chance to get into IHM Kolkata.

Hope you get the idea.

Thank You.
